If two functions are inverses of each other, which 2 statements are true?
group of answer choices

a) f(g(x)) = x and g(f(x)) is equal to x

b) the graph of an inverse of a function is a reflection of the function across the line y=0.

c) the graph of an inverse of a function is a reflection of the function across the line y=x.

d) f(g(x)) = x and g(f(x)) is equal to 1

A and C

Step-by-step explanation:

For 2 functions f(x) and g(x) to be inverses of each other, then

f(g(x)) = g(f(x)) = x → A

Given the graph of f(x) then the graph of it's inverse is obtained by reflecting the graph of f(x) in the line y = x → C

A and C

Step-by-step explanation:

We are given that two functions  are inverses of each other.

We have to find two statements are true about given functions.

Suppose f(x) and g(x) are two functions which are inverses to each other.

When f(x) and g(x) are inverses to each other then

A. and

Suppose f(x) =x+2 and g(x)=x-2

f(x) and g(x) are inverses to each other

Hence, option A is true.

Suppose ,

Replace x by y and y replace by x

Replace y with

Then, we get

Therefore, the graph of an inverse of a function is a reflection of the function across the lines y=x

A and C
